I hope this is in the right place? I am hoping to enlist some of your expert earth scouring assistance!

I have found this (old?) canvas of an aerial shot of an unnamed city and I am painstakingly trying to find out where it is (driving me mad!). There aren't many clues to go from, bar the 2 stadia, so it isnt easy! The earth (to the left where the city tapers out) seems reddish, which led to look at africa first (plus the shape of the main stadium) but so far no joy! Also the water looks very dark, so perhaps the mouth of a river or a lake rather than the sea? (though the shot looks to have been taken in the evening)

Any help/pointers would be greatly appreciated!
